class simvx.editor.panels.curve_editor.CurveKeyframe(time: float, value: float, tangent_mode: simvx.editor.panels.curve_editor.TangentMode = TangentMode.AUTO, tangent_in: float = 0.0, tangent_out: float = 0.0)

Extended keyframe data for curve editor with tangent handles.

Tangent values are stored as slopes (dy/dx in value/time space). Positive tangent = curve going upward to the right.

class simvx.editor.panels.curve_editor.CurveEditorPanel(editor_state=None, **kwargs)

Bases: simvx.core.Control

Animation curve editor panel.

Displays animation tracks as continuous bezier curves with editable tangent handles. Supports zoom, pan, keyframe selection/dragging, tangent editing, and a right-click context menu.

Args: editor_state: The central EditorState instance (optional).

Initialization

ready()

Connect to editor state signals.

set_player(player: simvx.core.AnimationPlayer | None, node=None)

Bind to an AnimationPlayer.

draw(renderer)

add_keyframe(track_name: str, time: float, value: float) → bool

Add a keyframe to the named track at the given time/value.

Returns True on success, False if the track doesn’t exist.

delete_keyframe(track_name: str, kf_index: int) → bool

Delete the keyframe at the given index from the named track.

Returns True on success.

set_tangent_mode(track_name: str, kf_index: int, mode: simvx.editor.panels.curve_editor.TangentMode) → bool

Set the tangent mode for a specific keyframe.

Returns True on success.

get_visible_tracks() → list[str]

Return list of currently visible track names.

set_track_visible(track_name: str, visible: bool)

Set visibility of a track.

get_selected_keyframe() → tuple[str, int] | None

Return (track_name, kf_index) of the selected keyframe, or None.
